[Effects of breast cancer cells stably overexpressing RSK4 on growth of transplanted human breast cancer in severe combined immunodeficiency mice].

Objective: To construct a breast cancer cell line MD-MB-231 stably overexpressing RSK4 gene and study its in vivo effects on tumor tumorigenesis.

Methods: The MD-MB-231 cells were transfected with pcDNA3.1/Neo and pcDNA3.
